Thank you, Mr. Chairman. Mr. Chairman, there is a potential risk here. For example, if the trend was starting to go up and we decided to buy in future markets a year or two years down the road, thinking that this trend is going up and will stay that way, and we purchased at that time and as it got time to deliver that fuel the price actually went below, we would end up paying the higher price. That's the risk in this. If the trend suddenly drops off, then we would take the hit on that. If we had this in place...We'll just use the example of this past summer's experience. We had a very large and fluctuating market. The increase climbed steadily over a number of weeks and months. In fact, daily changes were happening and if we ended up two years prior buying on a future market and hit that price on a high end...It has since come down, as we've seen in the private markets. We would be paying that higher price. So that is the danger of that, and we would have to make sure what we put in place, and our estimates used in watching the market would have to be finely tuned. Thank you.
